Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle transmission systems, in particular to a butterfly-shaped elastic plate. Background Art
[0002] The elastic plate is located between the engine and the torque converter, and the engine power is transmitted to the torque converter through the elastic plate. The working principle is that one side of the elastic plate is connected to the flywheel of the engine, and the other side is connected to the torque converter pump seat. The engine power is transmitted from the flywheel to the elastic plate, and then to the pump seat through the elastic plate. The pump seat and the pump wheel are an integrated structure to complete the power transmission. At present, most elastic plates are plate structures.
[0003] The current elastic plate has the following problems. When the torque converter is equipped with engines of different brands, the axial length of the torque converter is different due to the different axial relative positions of the engine flywheel and the flywheel housing. Different torque converters need to be designed to achieve the installation of the elastic plate. For example, the depth of the flywheel of the Quanchai engine is about 7mm recessed into the flywheel housing, while the height of the flywheel of the Kubota engine protrudes from the flywheel housing by about 10.5mm. Therefore, when the two engines are equipped, the axial size difference is 17.5mm. The existing common elastic plate structure cannot be installed to meet the use requirements. It is necessary to design torque converters with different axial lengths, which increases the production and manufacturing costs. For this reason, a butterfly elastic plate is proposed. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a butterfly-shaped elastic plate, comprising an elastic plate, wherein the elastic plate comprises a first mounting plate, an inclined mounting plate and a second mounting plate which are integrally arranged, wherein the inclined mounting plate is arranged along the side of the first mounting plate, and the second mounting plate is arranged along the side of the inclined mounting plate away from the first mounting plate, and through holes are provided on the surfaces of the first mounting plate and the second mounting plate.
[0006] As a further solution of the utility model: the first mounting plate is connected to the torque converter pump wheel seat, the torque converter pump wheel seat is provided with a torque converter shell, and the end face of the second mounting plate is connected to the engine flywheel, and the engine flywheel is provided with an engine flywheel shell fixedly connected to the torque converter shell.
[0007] As a further solution of the utility model: a plurality of pads are arranged along the edge of the second mounting plate, and the pads are provided with bolt holes which penetrate the through holes on the second mounting plate.
[0008] As a further solution of the present invention: the wall thickness of the elastic plate is designed to be 2 mm.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] 1. Through the interaction between the first mounting plate, the inclined mounting plate and the second mounting plate, the engine flywheel and the engine flywheel housing with different axial relative positions can be satisfied. Compared with the existing situation, it is necessary to design torque converters with different axial lengths, which increases the production cost. The present application greatly reduces the development cost of the torque converter by designing a butterfly-shaped elastic plate that matches its depth, and is beneficial to the unified design of the torque converter. It can also meet the needs of matching different engines and adapt to different axial sizes to reduce the types of torque converters. BRIEF DESCRIPTION OF THE DRAWINGS
